please help!

i've been having problems recently. i run xp home edition and my task manager and regedit has been "disallowed by administrator". other people have told me to run gpedit.msc, but i don't run xp professional. here's my log, please check it and reply with any suggestions, thank you very much.

hello, i am having several problems as of late. i run XP home edition. i cannot open task manager or regedit because they have been "disallowed by administrator". however, i am on an admin account. i am also getting many pop-ups. my homepage also changes every time i open my browser. i think that may be caused by CW, but the CWshredder failed to fix it. anyway, here is my HijackThis log. any help would be much appreciated. thank you.

i'm not exactly sure what kind of problem i have but no one is helping me in the other forums. please forgive a noob ig i am posing this in the wrong forum. anyway, i'm not sure of what's wrong with my computer (i run XP home edition, by the way). i just know that my task manager and regedit have been "disallowed by administrator". however, i'm on the admin account. anyway here is my HijackThis log. (any help would be greatly appreciated, thank you.)
